Plants from the Convolvulus genus are hardy annual or hardy perennial vines.
They have heart shaped leaves, some varieties flower but for one day, with trumpet flowers (can be blue, white, pink or purple).
Many gardeners consider most Convolvulus plants to be weeds. Though some species of Convolvulus such as Silverbush and Dwarf morning glory are grown.
The annual varieties of Convolvulus flower from summer to autumn, whereas the perennials flower in the summer.
How to grow Silverbush
If planning to grow Convolvulus outside from seed then they should be planted at a depth of 3mm into a sunny part of the garden in the middle of spring. Germination takes about one to two weeks. If growing Silverbush or other Convolvulus plants indoors, then the seed should first be chipped with a knife and soaked in warm water for a full day beforehand. They should be planted into peat pots in an area with a temperature of 22 to 28 degrees centigrade about two months before putting out.
Caring for Convolvulus
The seedlings of small species of Convolvulus should then be transplanted outdoors after the last frost of spring. If you require more plants then cuttings of Convolvulus can be took in the summer.
